The Yadana pipeline is a transboundary natural gas pipeline linking Myanmar 's Yadana gas field to Thailand . Built from 1995 to 1998 with the support of Thailand through the Petroleum Authority of Thailand , the project was subject to controversy over human rights abuses against minority groups in Myanmar and environmental concerns in Thailand. It supplies about 25 percent of Thailand's natural gas demand.

The Yadana Gas Pipeline in Thailand
88-561: A dominant language in all aspects of society in Thailand, Thai initially saw gradual and later widespread adoption as a second language among the country's minority ethnic groups from the mid-late Ayutthaya period onward. Ethnic minorities today are predominantly bilingual, speaking Thai alongside their native language or dialect. Standard Thai is classified as one of the Chiang Saen languages—others being Northern Thai , Southern Thai and numerous smaller languages, which together with

220-533: A four-way distinction among stops and affricates . The maximal four-way occurred in labials ( /p pʰ b ʔb/ ) and denti-alveolars ( /t tʰ d ʔd/ ); the three-way distinction among velars ( /k kʰ ɡ/ ) and palatals ( /tɕ tɕʰ dʑ/ ), with the glottalized member of each set apparently missing. The major change between old and modern Thai was due to voicing distinction losses and the concomitant tone split . This may have happened between about 1300 and 1600 CE, possibly occurring at different times in different parts of
264-545: A gas meter station and a SCADA Telecommunications system that was connected to the Petroleum Authority of Thailand's (PTT) existing SCADA system. After its completion the Yadana Gas Pipeline secured PTT with an alternative source of gas supply form Myanmar in addition to the Gulf of Thailand, on which PTT had totally relied upon.

At Scraper/Block Valve Station 1 located 350 meter away from the border the pipeline increases its diameter to 42 inch. It than transports the gas to the Ratchaburi Power Plant located at the end of the 240 km long pipeline. PTT's Operation and Maintenance Center
484-525: A syllable that formerly began with a voiceless consonant (including glottalized stops). An additional complication is that formerly voiceless unaspirated stops/affricates (original /p t k tɕ ʔb ʔd/ ) also caused original tone 1 to lower, but had no such effect on original tones 2 or 3. The above consonant mergers and tone splits account for the complex relationship between spelling and sound in modern Thai. Modern "low"-class consonants were voiced in Old Thai, and

A recent research found that the speakers of the Northern Thai language (also known as Phasa Mueang or Kham Mueang) have become so few, as most people in northern Thailand now invariably speak Standard Thai, so that they are now using mostly Central Thai words and only seasoning their speech with the "Kham Mueang" accent.

The payments were made from 2003-2013 and related to contracts for equipment and after-market products and services. Admitting its guilt, Rolls-Royce paid US$ 170 million to settle
880-547: The Khmer system first before the Thai borrowed. Old Thai had a three-way tone distinction on "live syllables" (those not ending in a stop), with no possible distinction on "dead syllables" (those ending in a stop, i.e. either /p/, /t/, /k/ or the glottal stop that automatically closes syllables otherwise ending in a short vowel).

According to PTT the Yadana Gas Pipeline is a highly sophisticated technical system and complies to the Thailand Quality Award (TQA) criterion. PTT did win
1012-484: The Thai-speaking area. All voiced–voiceless pairs of consonants lost the voicing distinction: However, in the process of these mergers, the former distinction of voice was transferred into a new set of tonal distinctions. In essence, every tone in Old Thai split into two new tones, with a lower-pitched tone corresponding to a syllable that formerly began with a voiced consonant, and a higher-pitched tone corresponding to

The crude oil spill had occurred 20 kilometres (12 mi) off Thailand's mainland, "when a floating hose transferring oil from a tanker to a PTT refinery pipeline broke sending 50,000 litres of oil spewing into the coastal waters". On 7 August 2013 media said that the Department of Special Investigation had seized an oil supply line, suspected of being faulty.

Bilingualism must have been strengthened and maintained for some time by the great number of Khmer-speaking captives the Thais took from Angkor Thom after their victories in 1369, 1388 and 1431. Gradually toward the end of
1276-547: The most significant changes occurred during the evolution from Old Thai to modern Thai. The Thai writing system has an eight-century history and many of these changes, especially in consonants and tones, are evidenced in the modern orthography . According to a Chinese source, during the Ming dynasty , Yingya Shenglan (1405–1433), Ma Huan reported on the language of the Xiānluó (暹羅) or Ayutthaya Kingdom, saying that it somewhat resembled

An oil leak (from a pipeline) 35 kilometres (22 mi) from Ko Samet 's Ao Phrao Beach, resulted in the beach being closed and its tourists evacuated after spillage reached
1364-415: The period, a language shift took place. Khmer fell out of use. Both Thai and Khmer descendants whose great-grand parents or earlier ancestors were bilingual came to use only Thai. In the process of language shift, an abundance of Khmer elements were transferred into Thai and permeated all aspects of the language. Consequently, the Thai of the late Ayutthaya Period which later became Ratanakosin or Bangkok Thai,

In December 2022, the Government Pension Fund of Norway divested from its equity stake in PTT and its subsidiary, PTT Oil and Retail Business, due to its human rights concerns regarding PTT's partnership with
1628-535: The terminology "low" reflects the lower tone variants that resulted. Modern "mid"-class consonants were voiceless unaspirated stops or affricates in Old Thai—precisely the class that triggered lowering in original tone 1 but not tones 2 or 3. Modern "high"-class consonants were the remaining voiceless consonants in Old Thai (voiceless fricatives, voiceless sonorants, voiceless aspirated stops). The three most common tone "marks" (the lack of any tone mark, as well as
1672-423: The two marks termed mai ek and mai tho ) represent the three tones of Old Thai, and the complex relationship between tone mark and actual tone is due to the various tonal changes since then. Since the tone split, the tones have changed in actual representation to the point that the former relationship between lower and higher tonal variants has been completely obscured. Furthermore, the six tones that resulted after
